Answer:
C) 36 km
Step-by-step explanation:
speed of Ruchir = 20 km/hr
time taken by Ruchir = 48 mins
distance covered by Ruchir = speed × time = 20 km/hr × 48min = 20 km/hr × 48/60 hr = 16 km
speed of Rukma = 25 km/hr
time taken by Rukma = 48 mins
distance covered by Rukma = speed × time = 25 km/hr × 48min = 25 km/hr × 48/60 hr = 20 km
distance between them when they started = total distance covered by both = 16+20 = 36 km
